This patch enables and starts the watchdog on the AT91 platform if
configured. The WD timeout value is read in the AT91 WD device driver
from the DT, using the "timeout-sec" DT property. If not provided in
the DT, the default value of 2 seconds is used.

This patch removes the CONFIG_AT91_HW_WDT_TIMEOUT as its not needed any
more. The WD timeout value can be provided via the "timeout-sec" DT

This patch fixes the timer register setup in at91_wdt_start() to
correctly configure the register again. The input timeout value is
now in milli-seconds instead of seconds with the new watchdog API.
Make sure to take this into account and only use a max timeout
value of 16 seconds as appropriate for this SoC.
Also the check against a lower timeout value than 0 is removed. This
check makes no sense, as the timeout value is unsigned.

This patch adds some checks, so that the watchdog can be enabled in main
U-Boot proper but can be disabled in SPL.
This will be used by some AT91SAM based boards, which might enable the
watchdog in the main U-Boot proper and not in SPL. It will be enabled in
SPL by default there, so no need to configure it there. This approach
saves some space in SPL.

This patch adds an alterative SPL version of atmel_serial_enable_clk().
This enables the usage of this driver without full clock support (in
drivers and DT nodes). This saves some space in the SPL image.
Please note that this fixed clock support is only added to the SPL code
in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL
should not be affected.
This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART
input clock. It defaults to 132096000 for ARCH_AT91 but can be set to
a different value if needed.

This patch adds a call to spl_early_init() to board_init_f() which is
needed when CONFIG_SPL_OF_CONTROL is configured. This is necessary for
the early SPL setup including the DTB setup for later usage.
Please note that this call might also be needed for non SPL_OF_CONTROL
board, like the smartweb target. But smartweb fails to build with this
call because its binary grows too big. So I disabled it for these kind
of targets for now.

When introducing the SAMA5D27 SoCs, the SAMA5D2 series got an additional
chip id. The check if the cpu is sama5d2 was changed from a preprocessor
definition (inlining a call to 'get_chip_id()') to a C function,
probably to not call get_chip_id twice?
That however broke a check in the macb ethernet driver. That driver is
more generic and also used for other platforms. I suppose this solution
was implemented to use it in 'gem_is_gigabit_capable()', without having
to stricly depend on the at91 platform:
#ifndef cpu_is_sama5d2
#define cpu_is_sama5d2() 0
#endif
That only works as long as cpu_is_sama5d2 is a preprocessor definition.
(The same is still true for sama5d4 by the way.) So this is a straight
forward fix for the workaround.
The not working check on the SAMA5D2 CPU lead to an issue on a custom
board with a LAN8720A ethernet phy connected to the SoC:
=> dhcp
ethernet@f8008000: PHY present at 1
ethernet@f8008000: Starting autonegotiation...
ethernet@f8008000: Autonegotiation complete

Notice the wrong reported link speed, although both SoC and phy only
support 100 MBit/s!
The real issue on reliably detecting the features of that cadence
ethernet mac IP block, is probably more complicated, though.

Enabling DM_MMC is forcing CONFIG_BLK=y so if any board which uses
SCSI must need to enable DM_SCSI otherwise SCSI reads on that particular
target making invalid reading to the disk drive.
Allwinner platform do support SCSI on A10, A20 and R40 SoC's out of
these only A10 have DM_SCSI enabled. So enabling DM_MMC on A20, R40
would eventually end-up with scsi disk read failures like [1]
So, enable DM_MMC in all places of respective SoC's instead of enabling
them globally to Allwinner platform.
Now, DM_MMC is enabled in Allwinner SoC's except A20 and R40.

This patch moves all instances of static "watchdog_dev" declarations to
the "data" section. This may be needed, as the BSS may not be cleared
in the early U-Boot phase, where watchdog_reset() is already beeing
called. This may result in incorrect pointer access, as the check to
"!watchdog_dev" in watchdog_reset() may not be true and the function
may continue to run.

RISC-V U-Boot expects the hart ID to be passed to it via register a0 by
the previous boot stage. Machine mode firmware such as BBL and OpenSBI
do this when starting their payload (U-Boot) in supervisor mode. If
U-Boot is running in machine mode, this task must be handled by the boot
ROM. Explicitly populate register a0 with the hart ID from the mhartid
CSR to avoid possible problems on RISC-V processors with a boot ROM that
does not handle this task.

On RISC-V, all harts boot independently. To be able to run on a
multi-hart system, U-Boot must be extended with the functionality to
manage all harts in the system. All harts entering U-Boot are registered
in the available_harts mask stored in global data. A hart lottery system
as used in the Linux kernel selects the hart U-Boot runs on. All other
harts are halted. U-Boot can delegate functions to them using
smp_call_function().
Every hart has a valid pointer to the global data structure and a 8KiB
stack by default. The stack size is set with CONFIG_STACK_SIZE_SHIFT.

Harts on RISC-V boot independently, U-Boot is responsible for managing
them. Functions are called on other harts with smp_call_function(),
which sends inter-processor interrupts (IPIs) to all other available
harts. Available harts are those marked as available in the device tree
and present in the available_harts mask stored in global data. The
available_harts mask is used to register all harts that have entered
U-Boot. Functions are specified with their address and two function
arguments (argument 2 and 3). The first function argument is always the
hart ID of the hart calling the function. On the other harts, the IPI
interrupt handler handle_ipi() must be called on software interrupts to
handle the request and call the specified function.
Functions are stored in the ipi_data data structure. Every hart has its
own data structure in global data. While this is not required at the
moment (all harts are expected to boot Linux), this does allow future
expansion, where other harts may be used for monitoring or other tasks.
